Table 2.
Comparisons of frequencies of higher carcinoembryonic antigen (CEA ≥ 3 ng/mL), squamous cell carcinoma antigen (SCC–Ag ≥ 2 ng/mL), and ferritin levels (≥250 ng/mL) between 41 patients with oral submucous fibrosis (OSF) and 164 age- and sex-matched healthy control subjects.
| Group | Patient number (%) |

|---|---|---|---|
| CEA | SCC-Ag | Ferritin | |
| OSF patients (n = 41) | 16 (39.0) | 8 (19.5) | 22 (53.7) |
| P-valuea | <0.001 | 0.001 | 0.001 |
| Healthy control subjects (n = 164) | 0 (0.0) | 0 (0.0) | 0 (0.0) |
